Management system for generating capacity and electricity consumption ratio of thermal power station

Abstract

The invention relates to a management system for the generating capacity and electricity consumption ratio of a thermal power station. The management system comprises a power station standard electricity consumption calculation module, a standard generating capacity and electricity consumption ratio calculation module, a generating capacity and electricity consumption ratio calculation module, a comparison module and a management module, wherein the power station standard electricity consumption calculation module is used for working out electricity consumption of the power station by establishing an electricity consumption standard formula of a boiler end and a steam turbine end, the standard generating capacity and electricity consumption ratio calculation module is used for figuring out a standard generating capacity and electricity consumption ratio by comparing corresponding generating capacities, the generating capacity and electricity consumption ratio calculation module is used for figuring out the generating capacity and electricity consumption ratio by means of practical electricity consumption, the comparison module is used for comparing the standard generating capacity and electricity consumption ratio with the generating capacity and electricity consumption ratio, the deviation between the standard generating capacity and electricity consumption ratio and the generating capacity and electricity consumption ratio is used as the deviation of the generating capacity and electricity consumption ratio, and the management module is used for evaluating and adjusting the current running status of equipment according to the deviation of the generating capacity and electricity consumption ratio. Compared with the prior art, the management system has the advantage that abnormal conditions of an auxiliary machine can be found early by evaluating the generating capacity and electricity consumption ratio.

Description

technical field [0001] The invention relates to an energy-saving technology for a thermal power station, in particular to a management system for the ratio of power generation and self-consumption power of a thermal power station. Background technique [0002] The production process of the thermal power station is to guide the steam produced in the boiler to the steam turbine, and drive the generator connected to the steam turbine to generate electricity. During this process, the auxiliary machines of boilers and steam turbines also consume a large amount of electric energy, which is called self-consumption electricity. Under normal circumstances, there is a relatively stable ratio between the power generation of power stations and self-consumption electricity, but with the increase of equipment operation time or the appearance of abnormal conditions such as poor maintenance quality, this ratio will show differences. If it can be tracked and evaluated, the abnormal situatio...
